DEVICE FOR LINING RAILROAD TRACKS.

Application filed September 7, 1922. Serial No. 586,721.

1 0 aZZ 20720777, it may concern.

Be it known that I, JOHN F. ELLIOTT, a citizen of the United States,residing at Al le-rton, in the county of l Vayne and State of Iowa, haveinvented certain new and useful Improvements in Devices for LiningRailroad Tracks, of which the following is a specification.

The present invention relates to a track liner or jack and the mainobject of this invention is to provide a device of this character, whichrequires a minimum amount of labor for handling, so that the railroadtrack can be properly lined with dispatch avoiding the use of a greatnumber of implements, which are ordinarily employed for this purpose.

lhe device is very strongly built without unnecessary weight and may behandled with ease and transported from place to place withoutdifiiculty.

These track lining jacks are used in pairs one under each rail oppositeto each other and the device is placed under the rail in such a manner,that when the rocking handle is pulled down, the so-called crowding barwill be raised and as it engages under the foot of the rail, the latterwill be slightly lifted and pushed over to one side. For this purposethe crowding bar has an inclined surface, the slope of which willgradually increase as the bar is raised compelling the rail to slidedown the incline and in this manner be pushed away from the jack.

In the accompanying drawing one embodi ment of the invention has beenillustrated and Fig. 1 is a vertical section of the device, and

Fig. 2 is a top plan view thereof, partly in section.

Reference numeral 10 represents a base consisting of a flat board orplate 11 preferably made of cast-iron and having sharp claw-like ledges12, one at each end of the base. At one end of the base are provided apair of bearings 13 in which the crowding bar 14 is fulcrumed upon ajournal 9 and the other end of the base has a pair of cheeks .15, inwhich a shaft 16 is mounted to revolve and upon which the operatinglever 17 is mounted.

This lever is preferably provided with a socket 18 for receiving ahandle 19 andha-s a segment 20 at its lower end furnished with teeth 21engaging with corresponding teeth 22 in the free end of the crowding bar14.

As shown in the drawing the ratio bet-ween the lengths of the radii forthe gear teeth 21 and 22 is substantially as one to four, so that with agood length of the handle 19, a considerable leverage will be obtainedonthe crowding bar 14:; Furthermore the upper face of the crowding baris curved as at 23, slanting downwardly from the upper-most tooth 22towards the fulcrumed end of the 1 bar for the purpose of wedging thebar under the foot of the rail 24. In swinging the handle 19 of thelever 17 in the direction of arrow X in Fig. 1 the crowding bar 14 willbe raised thus forcing the foot of the rail upwardly and inwardly untilthe correct position has been found.

It will be noted that the device is very substantially built and onlyconsists of five solid parts, which cannot readily be broken or get outof order and any of which parts, however, may be quickly replaced byothers in the case. of injury.

Having thus described the invention, what is claimed as new is:

1. A track lining jack comprising a base, ground-engaging members onsaid base, a crowding bar fulcrumed on the base, a rocking leversimilarly fulcrumed on the base, and interengaging means between saidlever and said bar for oscillating the latter, said crowding bar havingan arcuate cam surface adapted to engage with the rails.

2. A track lining jack comprising a base, ground-engaging sharp edgedledges on said base, a crowding bar fulcrumed on the base, a rockinglever similarly fulcrumed on the base, and interengaging means betweensaid lever and said bar for oscillating the latter, said crowding barhaving an arcuate cam surface adapted to engage with the rails, and saidinterengaging means including toothed segments integral with saidrocking lever and said crowding bar respectively.

3. A track lining jack comprising a base, ground-engaging sharp edgedledges on the under side of said base, bearing members on said base, acrowding bar between said bearing members, a journal carried in saidmembers and in which the crowding bar is fulcrumed, a pair of cheeks onthe other end of said base, a shaft mounted in said cheeks, a rockinglever fulorumed on said shaft, a toothed segment integral With saidrocking lever, a oorrespondingly-toothed segment integral with saidcrowding bar and meshing with said first toothed segment, and saidcrowding bar having an arouate cam surface 10 adapted to engage underthe foot of a rail. In testimony whereof I afiiX my signature.
